Hide Default Product Template field and set Category Template default

Hi,

I’m trying to set the Category Template but it’s not working. I’ve set the Template in System Settings but when i right click the ‘Create A Simplecart Category Here’ it adopts the Shop Template.
I’ve tried adding the Tempate number into Manager Customization but this doesn’t work either.
What else can i do to set the default Category template?

I would also like to hide the Default Product Template field from the Category resource - how can i do this?

Thanks for any help
